摘要: 20CrMnTiH钢的工艺流程为100t转炉-LF-VD-方坯连铸-轧制。通过采取提高转炉出钢[C]≥0.08%,优化LF精炼渣系,控制渣中CaO/Al2O3 1.5~1.7,用喂SiCa线代替喂Ca线,防止钢水二次氧化等措施,20CrMnTiH齿轮钢氧含量0.0015%~0.0019%和夹杂物级别≤1.5。
Abstract: The process flowsheet for steel 20CrMnTiH is 100 t BOF-LF-VD-bloom casting-rolling. By improving converter tapping [C] ≥08% , optimizing refining slag system, controlling the CaO/Al2O3 in slag 1. 5 to 1. 7 ,using feeding SiCa wire to replace feeding Ca wire and preventing secondary oxidation of molten steel in casting, the oxygen content in gear steel 20CrMnTiH is 0.0015% ~0. 0019% and rating of inclusions in steel is ≤0.5.
